"Ideally the future"
When, how ?
Yes ideally the future can have magical technologies that will solve humanity problems. We had this magical "nuclear" thing in the sixties. Today a huge majority of electricity worldwide is produced by coal, oil and gaz.
Hydrogen is a no go, you're loosing 70% into transforming electricity to hydrogen and back to electricity. And no you cannot simply "throw money at it" to turn 70% into 5%.
- Amarok 7y agoThis is just plain desinformación, hydrogen has an efficiency of 70%, which means a loss of 30%, and yes this figure is improving by "throwing money at it"

- Amarok 7y agoThis article is 2 years old and rather misleading. The battery electric vehicle itself is much less efficient than both the fuel cell electric and conventional vehicles. This is because of the weight of the batteries that need to be transported. If you also take into account the energy used to produce the vehicles, in particular, the batteries, the BEV becomes the least efficient of the 3. It also doesn't account for on site hydrogen production and PEM or Alkaline technologies, which reduce the losses in transport, production and compression for an 86% efficiency.
